Audit of technical integrity of aging facilities in Statoil

During the period 22 September - 11 October 2006, the Petroleum Safety Authority Norway (PSA) conducted an audit of how Statoil safeguards the technical integrity of load-bearing structures on the Statfjord field. No nonconformities were identified during the audit.


Background for the audit

The audit is based on the PSA's performance goal in relation to following up the risk of major accidents. This is an activity that falls within the PSA's prioritized follow-up of the petroleum industry's work on technical condition and aging facilities.

The purpose of the audit was to verify that Statoil has management systems that reduce the risk of structural failure on aging facilities, and that Statoil has qualified solutions to handle the technical integrity of load-bearing structures so that the intention in prevailing regulations is safeguarded.

The task included Statoil's follow-up of the supervisory duty vis-à-vis its suppliers.

Result of the audit

Statoil has established a process for safeguarding the technical integrity of load-bearing structures, and procedures have been established to manage this process.

No nonconformities were identified during the audit, but we have identified several areas where there is a potential for improvement. These are:

  • Controlling documents in connection with safeguarding the technical integrity of load-bearing structures.

  • Organization and safeguarding of responsibilities, authority and competence.

  • Acceptance criteria in connection with which structural incidents and damage that entail establishment of emergency preparedness.

  • Monitoring and maintaining an overview of the condition of structures.
